1 Samuel 2:13-14

13or for the custom of the priests with the people.

When any man offered a sacrifice, the servant of the priest would come with a three-pronged meat fork while the meat was boiling 14and plunge it into the pan or kettle or cauldron or cooking pot. And the priest would claim for himself whatever the meat fork brought up. This is how they treated all the Israelites who came to Shiloh.
